The hardened steel extruder unit is equipped with double gears made of hardened steel, which provides increased extrusion force, prevents slippage, and enhances abrasion resistance. These gears enable the extruder unit to handle tough engineering filaments such as carbon fiber nylon and glass fiber nylon.
In addition, the extruder unit includes a sensor that supports filament break detection, which can help prevent print failures and improve overall printing efficiency.
